Application filed May 5, 1913. Serial No. 765,616.

To all whom it may concern.

Be it known that we, Airri un Pnanr Honors and PnILIr MORGAN, of the city of Toronto, in the county of York and Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Folders for WVrapping-Machines; and we hereby declare that the following is a full, clear, and exact, description of the same.

Qu'r invention relates to an end. folder which will uniformly shape the end folds of a. tubu-lar wrapper irrespective of the unifornrity of shape or size of the article it contains, and the object of our inwention is to so constructand operate the end folder that it will exteriorly engage one side of the wrapper andfold that side against the article, and then interiorly engage the wrapper-mild simultaneously fold all the re ma'i-ning sides to effect the sealing of the package ends, the folder during such interior engagement with the wrapper operat ing as a former to define the lines along which the folds are made.

In the drawingsz-Figure l is an elevation of a folder; Fig. 2 is a plan view of the COI-lStl'llL'tlOll shown in Fig. 1; Fig. 3 is an elevation of the folder shown in Fig. 1 with its parts in their contracted position; Fig. 3 is a perspective view of a partlywrapped package showing the formation of the fold when the folder parts are in the position shown in Fig. 3; Fig. 4 is an elevation of the folder shown in Figs. 1- and 3 with its parts in the position shown in Fig. perspective view of a wrapper showing the formation of the folds when the folder parts have assumed the position shown in Fig. 4: Fig. 4" is a perspective view of the wrapper when the peak folds have been closed against the ends of the package. the closing of the peak folds, however, being by means supplemental to the folder; Fig. 5 is an elevation of a modification of the folder shown in the preceding views with its parts in their contracted position. this folder forming the same style of fold as that shown in Figs. 3 and 4; Fig. fi is a perspective view of a wrapper showing the formation of the folds when the folder parts are in the position shown in Fig. 5; Fig. 6 is a. similar view to Fig. 5 with the folder parts in their extended posi- Fig. 6 is a engage and fold one side of fine the lines tion; Fig. 6 is a perspective. view of a wrapper showing the folds when the folder parts are in the position shown in Fig. 6; perspective view of the wrapper with its ends sealed; and, Fig. 7 is a. similar view to Fig. 6 showing the same style of folder as shown in the preceding view, with a slight change in the conformation of the fold-forming parts.

The folders hereinafter described and illustrated in the accompanying drawings have been particularly designod'for use in connection with a wrapping machine in which the articles to be wrapped may be either of a uniform or non-uniform shape and size, and are the result of a' series of exhaustive experiments with regard tothe formation of the end foldsof a wrapper containing an irregular-shaped package, we having discovered during these experiments that it was necessary to constructand arrange the folder so that it Would exte'riorly the wrapper and then interiorly engage and\supp0rt the remaining sides of the wrapper during the formation of the rmnainder of the folds, and during such interior engagement, de-

of said folds.

The folder shown in Fig. 1 consistsof a substantially rectangular fold-forming element f and two fold-forn'ling elements f hingcdly connected to the sides of the foldforming element 7' and extending to the top thereof. The fold-forming elements f are so hinged to the fold-forming element f that they can be turned to lie flat against the fold-forming element. 7", or approximately so, as shown in dotted lines in Fig. 1 and in full lines in Fig. 3. or extended into the same plane as the fold-forming element f, as shown in full lines in Figs. 1 and 4. -Each of the fold-forming elements f is provided with a rod g. at the lower end of each of which is a pinion h engaged by a reciprocating rack z, the movement of which turns the fold-forming elements f to lie against the fold-forming element f, as shown in Fig. 3, or to extend the fold-forming elements f into the same plane as the foldforming element f, as shown in Figs. 1 and 4.

When the folder shown in Figs. 1, 2, 3 and 4: is brought into operative relation with the wrapper, the fold-forming'element 7' exteriorly engages the side j of the wrapper and folds it to lie against the end of the article as shown in Fig. 1-3. The top edges of the fold-forming element f, when the folder has reached its limit of movement, is approximately opposite the top of the article and interiorly in. contact with the interio rl y side y" of the wrapper, and in this position,

its side'edges 7) are interiorly in engagement with the wrapper sides 9' to define the lines of the folds. When the fold-forming element 7' has reached its limit of movement, the rack i is operated to cause the pinions h and rods g to oscillate the fold- :l'orining elements ffrom the position shown in dotted lines in Fig. 'l and full lines in Fig. 3 to the position shown in full lines in Figs. 1 and 4, the fold-forming elements 7* as they move to this latter position, engaging the sides 7' to complete the formation of the peak folds k which, in this case, are located at the vertical sides of the wrapper. The edges f of the fold-forming elements 7 are inclined to co'rrespond with the inclination f the sides of the peak folds 70. In fact, the fold-forming elements f may be of a triangular shape. as indicated by the dotted lines m joining the sides 1 with the bottoms of said elements. During the movement of the fold forming elements f from their normal position to their exengage and fold tended position, theypress interiorly against the sides 7' and tension the wrapper as they draw the sides of the wrapper to the peak folds in, the fold-forming element 7 during this act-ion of the fold-forming elements f, serving as an interior former and support for the wrapper folds.

, in Figs. 5 and 6, the fold-forming elements Z. Z are similar to the fold-forming elements 7, f, but instead of the fOlClfOLHP ing elements Z, Z being oscillatingly hinged, they have a reciprocating movement with relation to the fold-forming element 1. this movement being provided by the triangular guide slots Z. in the fold-forming element Z and the guide pins on for the fold-forming elements Z operating, in said slots. The style of the fold and the method of making it are the same as in regard to the folders shown in Figs. 1, 2, 3 and 4. In Figs. 5 and 6, the fold-forming elements Z are shown to be provided with inclined sides m, but as in the previous case, these fold-forming elements may be of a triangular shape, as indicated by the dotted lines m" in those views.

In Fig. 7, the folder is similar to that shown in Figs. and 6 and operated in the same way, but the foldorming elements 0' have curved sides 0". I

The above description may be briefly summarized as follows By making folder of two or more movable into a contracted position when the I nected thereto and a fold-forming elements folder comes into operative relation with the wrapper, itis possible to enable the folder to cxteriorly engage one side of the wrapper and fold it to the article, then v engage the wrapper, and by the expansion formation of a plural number of folds and complete, at a single operation of the folder, the closing of the end of the wrapper preparatory to the peak fold or folds being sealed, one of the during such action, defining the lines of the folds and therefor.

Having thus fully described the nature of our invention, what we claim 215116 and desire to secure by Letters Patent, is

1'. A folder comprising a fold-forming element to exteriorly engage and fold one side of a tubular wrapper andthen enter interiorly of its remaining sides to define the lines along which they are to be of its component parts, effect the fold-forming elements serving as a former and support folded,

A folder comprising. a fold-forming element to close one side of a tubular wrapper and then enter interiorly of its remain-- ing sides to define the lines of the folds and serve as a former and support therefor, andfold-forming elements cooperating therewith to interiorly engage the; wrapper and, by tensioning it, effect the formation of the folds along the lines so defined.
